Application 'flled July 8,

1921 Serial No. 483,145.

' (GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. '14., 1313.)

To all whom it may concern:

Be it known that I, HEINRICH Korruns (assignor to The Koppers Development Corporation, a corporation of lennsyl- 5 Vania), a citizen of Germany, res1ding 1n Essen-Ruhr, Germany, have invented a new i and useful Improvement in Coke Quench ng and Loading Devices (for which applicatlon for patent has been filed in Germany on or about March 18, 1.920), of which the following is a specification. 1

A prior design (not claimed in my present application) relates to a coke quench ng and loading device, by means of a quenchmg car with a slanting bottom and a stationary ramp adjoining the same and inclined at about the sliding angle of the coke, to WhlCh' the coke can be transferred or conveyed without a free fall and where it spreads out V in a comparatively thin layer, so that it can ,Je quenched. and discharge the vapors as may be required. The entire arrangement 1s based on the'gniding principle of vouchsafing an economical quenching of the coke,

and'as gentle a treatment or handling of it as possible during the transfer. According to another prior design (not claimed in my,

present application) the ramp constitutes the medium between the quenchmg car and the screening device, there being arranged in front of the ramp a movable screening device which has a bucket elevator extending thereunder for the purpose of receiving the coke as needed.

the stationary ramp to the height of the screening device, it is advisable in many cases to arrange the ramp itself at the proper height above the screening device and to lift 40 the coke the level 0 the ramp. The idea of doing this by elevating the quenching car itself for the reqluired distance, for instance by the use of, .inc inedplanes, meets with practical difiicuL' ties for the reason that the quenching car is extremely hea In order to be able'to resist the action 0 the glowing coke, the en'- tire quenching car must be built heavy and solid; thus, for instance, its lining of heavy cast plates is absolutley essential. The lift-' ing of this dead weight, especially together with the entire charge of such a quenching buckets and standard railway cars.

Instead of conveying the coke first from uenched in the quenching car to mitted to slide off from said intermediate receptacle to the latter. Since these intermediate receptacles do not come into contact with unquenched coke, they can be built lighter than the coke quenching cars themselves; furthermore it is possible to subdiyide these intermediate receptacles into several smaller ones 'for receiving the charge from a coke uenching car, whereby the amount of lifting energy required is still further reduced.

Since for practical reasons the screening device to be arranged at the end of this stationary throw-01f ramp comprises individual screens to be operated by themselves, for instance in theshape of roller grates which can be started or stopped by means of stowing rakes or the like, the possibility is at once afi'orded of loading both blast furnace subdivision of the screening devices in this connection is from the first carried out and dimensioned in such a way that the blast furnace buckets. disposed in the customary manner in a certain number, for instance in sets of five on a common truck, can be loaded simultaneously and uniformly by operating all of the screening devices, while for loading railway cars the central screening The devices, for instance, can be 'put out of com iw,

mission in order to avoid a spilling oftheic coke in the space between the two railway" cars.

In order to prevent, especially in connection with the charging of blast furnace buckets, asubsequent breaking up of the coke such as is easily broughtabout by a great height of fall, an auxiliary arrangement is provided here which consists of an auxiliary chute assigned to the discharge or outlet of is shown in the accompanying drawings a practical use of the same.

In said drawings.

Fig. 1 is an elevation, partly in section, of a coke quenching and loading device embodying the invention.

Fig. 2 is a plan view of the same.

Figs. 3, 4: and 5 show, on a larger scale, the auxiliary arrangement, in various positions, for charging the coke into blast furnace buckets.

Fig. 6 is a fragmentary perspective view showing a plurality of stowing rakes associated with the roller grate screens, and showing the subdividers. I

Fig. 7 is a perspective View of the auxiliary chute.

The coke coming from the oven 10 and pressed on to the quenching cars 11 with slanting bottoms is taken to the quenching station and quenched there by irrigation.

The car then goes in front of the frame 12 in which the receptacles 13 are arranged, which also possess a bottom inclined at the sliding angle of the coke and which can thus be loaded without injuring the coke. In order not to make the individual receptacles 13 unduly heavy in this connection two such are provided in each case for the length of the quenching car 11.. A spur 14 which works after the fashion of an ice pick or breaker, sees to it in this connection that the load of the quenching car 11 is uniformly distributed between the two receptacles 13. By means of the winches 15 the receptacles 13 are lifted fm: enough in the frame 12 to make their lower edge flush with the upper edge of the slanting stationary platform 16, so that the coke can slide from said receptacles over on to this platform, where it spreads out to discharge the vapors or to be after-quenched. At the lower end of the platform 16 the roller grates or screens 17 five in number as shown, are arranged, between which, also after the man; ner of ice breakers, subdividers 18 are pro vided. By means of the stowing rakes 19 the individual roller grates 17 can be closed off from the platform. 16. Underneath the grates 17 the receptacles 20 are arranged for the reception of the finely screened coke and can be emptied, as required, onto a conveybelt 21 or the like.

According to the opening of the stowing rakes 19 and the operation of the roller grates 17 it is possible to discharge the coke at the desired places, so that, for instance, by operating all of the roller grates 17 it is possible to charge the blast furnace buckets 23 likewise arranged in sets of five on a common truck 22. By means of the subdivision described, the feeding of the coke in the requisite quantity for each bucket is insured. The loading of standard railway cars can be effected by only utilizing perhaps two or three of the roller grates 7 or by disconnecting the central roller grate in connection with railway cars st'anding in series, in order to prevent a spilling of the coke between the railway cars.

Under the discharges 24 of the individual roller grates 17, are provided the auxiliary chutes 25 which are provided with elongated slots intermediate their sides and extending a short distance toward the top of the chute so that when the chute is lowered to the position shown in Figure 3 the hanger rods 26 will extend through said slot and allow the chute to enter into the buckets 23. These chutes 25 are so movably supported that they can assume consecutively the positions shown in Figs. 3 to 5, so that the coke describes a zig-Zag route (with little fall),

which not only prevents its being broken up but also insures at the same time a filling of the buckets 23.
